Beacons being lit

The Queen will be in Windsor to light the first of more than 900 beacons in the UK and around the world.

Air Cadets will light a beacon at the top of Snowdon as part of festivities today while others will be lit in Swansea, Wrexham and Llantrisant.

The National Beacon of Wales will also be lit in Cardiff Bay, followed by fireworks from 8pm.

Gun Salutes

A special 21-gun salute will take place in the capital, at Cardiff Castle.

The 21-gun salute will take place at midday and there will be a drinks reception for other people celebrating milestone birthdays and anniversaries.

Visitors to Cardiff Bay can get a complimentary glass of Prosecco with strawberries if they are dining at the Bayside Brasserie tonight.

Cardiff Lord Mayor, David Walker, said: “Cardiff has a long and unbroken tradition in joining the rest of the country to celebrate Royal Jubilees, weddings, coronations and special birthdays with the lighting of beacons previously taking place in Cardiff Castle and Flat Holm.

“This is a wonderful opportunity for people to come together and commemorate her Majesty’s milestone.”

Erm, giant models of the Queen’s head?

Around 40 giant fibreglass models of the Queen’s head are being displayed at a farm in Flintshire.

David Pickering won lottery funding to create them for the Diamond Jubilee in 2012.

He has decided to display them again on his land near Higher Kinnerton as the nation pays tribute to Britain’s longest-serving monarch.

The royal superfans who travelled through the night from Wales to Windsor to wish the Queen happy birthday:

Afternoon tea

Toast the Queen, the quintessentially British way, with tiny sandwiches, cakes and loads cups of tea (or a gin and tonic).

Classic brasserie, Le Monde , kicks off its new tea service this Thursday with their Afternoon 9-T Party - where a right royal spread will be laid on alongside Bombay Sapphire gin and tonics.

The restaurant is launching an afternoon tea service on Friday and Saturdays - and more details can be found out by ringing 029 2038 7376

Joining in the celebrations with royal-tea is the New House Hotel in Cardiff , too. It will include a Gin and Dubonnet Cocktail (a favourite of the Queen), and a savoury selection including smoked salmon blinis, mini lamb burgers, and mini beef and Yorkshire puddings.
